A project that has occupied me for years without being able to tackle it - for lack of a replacement display and know-how.
Now it's implemented
With my most beautiful F3/T (never used before), I had to watch the LCD display in the viewfinder slowly but steadily disappear.
At first, only individual digits failed - eg. the plus sign was no longer displayed in the event of overexposure.
Well, I could get by with that, although not ideally.
But then all the digits started to fade.
Today I saw that whole digits are no longer displayed completely.
This nice F3/T could therefore only be used with an external exposure meter or for the closet.
Since I had meanwhile collected three F3 for parts that still had their Displays installed, I dared to intervene today.
Replacing the LCD
My donor F3 came to me already partially looted.
Since, among other things, the shutter release was missing, I could not test whether her LCD was still intact.
The electronics were already open, so I didn't want to insert a battery. Who knows what the previous owner did to this F3 …
Since the left housing cap was already removed, I only had to loosen four screws to remove the LCD unit, which was then only attached to the flexible circuit board.
Here is the unit with the bottom cover already removed:
In detail - the famous red button for illuminating the LCD on the far left.
On the right the still covered LCD block with the light inlet to the outside for the display:
After removing the cover plate, the LCD block can be seen:
The LCD block can be easily pulled out.
Below the contact strips located on the board:
The donor part for my F3/T.
Above the two rows of contacts on the LCD block two strips of soft, transparent plastic are placed:
The piezoelectric element (below) with contact plate for the viewfinder illumination:
The contact plate comes back into place.
Simply insert, no further attachment:
The arrow shows the position of the small plate between the red push button and the gray piezoelectric element:
The bottom cover for the LCD unit and the LCD block:
The donor in the front, the recipient in the back:
I worked my way to the left case cap on the F3/T to be able to pull out the LCD assembly with the flexible circuit board a bit.
These three lightning contact shoe cables must be unsoldered:
The donor LCD is installed in the F3/T and the left housing cap, the override with the flash contact shoe as well as the rewind crank are installed.
Before installing the LCD, I cleaned the two rows of contacts on the flex circuit board with isopropyl alcohol.
The anxious moment - was the transplant successful?
Yes!
A high-contrast LCD display now shows all digits again!
My resurrectedF3/T, almost written off, is back in full force

The defective LCD with obvious signs of decay on the contact rows:
